Tricorne

Hat with the brim turned up on three sides

The tricorne or tricorn is a style of hat in a triangular shape, which became popular in Europe during the 18th century, falling out of style by the early 1800s. The word "tricorne" was not widely used until the mid-19th century. During the 18th century, hats of this general style were referred to as "cocked hats".
